Data transmission refers to the process of sending data from one location to another over a communication channel. It involves encoding the data into a suitable format, transmitting it through a physical medium or a network, and then decoding it at the receiving end to retrieve the original information. Data transmission is a fundamental aspect of data communications and plays a crucial role in enabling the exchange of information in various computer networks and systems.
When it comes to transmitting data, it is necessary to convert the data into a form that can be efficiently transmitted and accurately reconstructed at the receiving end. This is where data encoding techniques come into play. Data encoding involves converting the original data into a structured format that facilitates efficient transmission and ensures data integrity.
There are several methods of data encoding used in data communications, each with its own characteristics and applications. Some of the commonly used methods include:
1. Unipolar Encoding: In unipolar encoding, the voltage level of the signal represents the binary values. For example, a high voltage level can represent a binary '1', while a low voltage lev....
